Yo, so, this is something I cringe about occasionally. If you look at my art circa 2006 (I won't bore you, but I have posted it on these forums before) and compare it to art in 2010, there's a MASSIVE improvement. And then... in the last 10 years... the improvement has been, ah, marginal at best.
Here's the thing though: in 2010 I was in second year university, where I first began to struggle with depression. In 2014 I had carpal tunnel and had to stop drawing for half a year. In 2016, I began having whole-body problems, massive pain and weakness in my arms that eventually spread to my legs. I could only draw MAYBE 30 minutes ON A WEEKEND (forget workday), with ONLY a pencil or watercolor, something that's light (I was able to draw on my PC sometimes, but only sketching, not inking). Nobody knew what was wrong with me. I thought I might never be able to draw again. So... I focused on doing what was fun and what got me through the day, not improvement.
I recently made drastic changes to my lifestyle and got serious about trying to diagnose the issue, and some solutions have allowed me to regain some use of my arms again. For a couple months, I could draw for an hour a day; at that point it became "Do I do a study, or do I draw in a way that makes me happy?" Because that was the choice. One or the other. Not both. It was painful, to be honest - psychologically. But I usually chose what made me happy, because at the end of the day, even if my studies were good, I only had 40-60 minutes I could draw. I wanted to draw what made ME happy (which was mainly my comic, and a couple of commissions for some close friends). If I'm being real, I thought maybe I was terminally sick (I'm, ah... still not sure). I wanted to draw stuff that I could look at, at the end of my life, and go "that makes me happy" rather than a portfolio full of studies and nothing to show for it. Because at the end what matters isn't the skill that dies with you; it's how that skill was able to reach other people. And I'd personally rather reach other people, even if my art isn't perfect, than achieve perfection that no one ever witnesses.
That's not to say I don't TRY to improve or don't agonize over my panel layout or the drawings within. But... if the choice is "draw imperfect comics that tell the stories inside my mind" or "do 3 hours of studies a day while dreaming about the day I'll be good enough to tell those stories".... the choice is obvious. Life is short. Might as well start doing the things you love now.
